Milling and paving repair operations for airport runways require particularly high tolerances, an obvious market for 3D control solutions writes Mike Woof. Airport runways require some of the most accurate quality standards and tightest tolerances of any asphalt or concrete surface. This is one area where the high precision capabilities of 3D systems offer clear advantages.

BOMAG says that its new BF800 paver has now been well proven in tough working applications.

Innovative materials testing technology will allow the road sector to boost pavement quality, Mike Woof and Patrick Smith report. With billions being spent on highway construction worldwide, governments are looking to make sure their investments last as long as possible.

Key additions will boost the asphalt paver offering for customers, Mike Woof reports. There are a number of key players in the asphalt paving market that see the value of investing in design, technology and performance. For customers this has resulted in a wide variety of high quality, high performance machines to choose from.

Increases in flight numbers from the Frankfurt Hahn airport have resulted in necessary improvements to the facility, including new runway surfaces. The former German military airbase has been used as a civilian airport since 1993 but is now Germany's fifth largest air cargo hub and handles some 40,000 flights/year.

Winter repairs The tough winter conditions in Canada play havoc with road conditions and this often results in problems such as potholes and longitudinal cracking. But Aquadyne Industries says it has found a solution with the introduction of infrared asphalt restoration equipment. The equipment from Ray-Tech Infrared can be used all year round to repair roads and is now carrying out valuable work in Canada due to the firm's local agent, Aquadyne Industries. These units offer an alternative to the traditiona
